Torque Lock
If you are parking on a hill and you do not shift
your transmission into PARK (P) properly,
the weight of the vehicle may put too much force
on the parking pawl in the transmission. You
may nd it difficult to pull the shift lever out
of PARK (P). This is called torque lock. To prevent
torque lock, set the parking brake and then shift
into PARK (P) properly before you leave the
driver’s seat. To nd out how, seeShifting Into
Park (P) on page 152.
When you are ready to drive, move the shift lever
out of PARK (P) before you release the parking
brake.
If torque lock does occur, you may need to have
another vehicle push yours a little uphill to
take some of the pressure from the parking pawl
in the transmission, then you will be able to
pull the shift lever out of PARK (P).
Shifting Out of Park (P)
Your vehicle has an automatic transmission shift
lock control system which locks the shift lever
in PARK (P) when the ignition is in the LOCK.
You have to fully apply your regular brakes before
you can shift from PARK (P) when the ignition
is in RUN. SeeAutomatic Transmission Operation
on page 144.
If you cannot shift out of PARK (P), ease pressure
on the shift lever and push the shift lever all the
way up into PARK (P) as you maintain brake
application. Then, move the shift lever into
the desired gear.

Mirrors
Automatic Dimming Rearview Mirror
with Intellibeam™, OnStar
®,
Compass, and Temperature Display
Your vehicle may have an automatic dimming
rearview mirror with Intellibeam, OnStar®, compass
and temperature display. For more information
on OnStar
®, seeOnStar®System on page 165.
For more information on Intellibeam™, see
“Intellibeam Intelligent High-Beam Headlamp
Control System” underExterior Lamps on
page 205.
The mirror includes an eight-point compass
display in the upper right corner of the mirror face.
When on, the compass automatically calibrates
as the vehicle is driven. Outside temperature
is also shown in the display.
Automatic Dimming
Your vehicle is equipped with an inside automatic
dimming rearview mirror. The automatic dimming
feature is activated whenever the vehicle is turned
on and dims only during nighttime driving.
Compass Operation
AUTO3:Press and hold the “auto highbeam”
button for approximately three seconds to turn
the compass/temperature display on or off.
When the ignition and the display features are on,
the display will show two character boxes for
about two seconds. After two seconds, the mirror
will display the compass heading and temperature.
Compass Calibration
If after two seconds the display does not show the
correct direction, (N for North for example),
there may be a strong magnetic eld interfering
with the compass. Such interference may be
caused by a magnetic antenna mount, magnetic
note pad holder, or a similar magnetic item.
The compass can be placed in calibration mode
manually by pressing and holding the “auto
highbeam” button for approximately nine seconds
until CAL is shown in the compass display.
The mirror can then be calibrated by driving the
vehicle in circles at 5 mph (8 km/h) or less until the
display reads the correct direction.
